Focused aquifer regeneration produced outsized gains for a threatened fish in a populated, dryland watershed Open
A combination of groundwater pumping and shifting precipitation patterns is drawing down aquifer levels in many of the world's drylands and is predicted to generate widespread loss of perennial streamflows over the next few decades. This p…

California steelhead populations were regionally buffered and individually resistant to a severe multi-year drought Open
Weather extremes, such as drought, are predicted to be a strong determinant of species persistence under climate change. Yet predictions often fail to consider that variation in streamflow responses, variation in population dynamics, or ad…

Poor downstream passage at a dam creates an ecological trap for migratory fish Open
Ecological traps can be caused when partial restoration leads organisms to make maladaptive habitat choices. One example of this is fishways (e.g., fish ladders) that provide upstream passage at dams but are not paired with adequate downst…

Quantifying partial migration with sex-ratio balancing Open
Partial migration, the phenomenon in which animal populations are composed of both migratory and nonmigratory individuals, is widespread among migrating animals. The proportion of migrants in these populations has direct influences on popu…

Population models with partial migration Open
Populations exhibiting partial migration consist of two groups of individuals: Those that mi- grate between habitats, and those that remain fixed in a single habitat. We propose several discrete-time population models to investigate the co…
